[0030] A slot 7 is provided at the bottom end of the left keyboard 1, a limit slot 8 is provided inside the left keyboard 1, a fixed block 10 is fixedly connected to the right end of the left keyboard 1, a pull-out slot 11 is provided inside the fixed block 10, an extension block 12 is slidably connected inside the pull-out slot 11, a first rotating shaft 13 is fixedly connected inside the extension block 12, an extension rod 14 is rotatably connected to the surface of the first rotating shaft 13, a second rotating shaft 15 is rotatably connected inside the extension rod 14, a support rod 16 is welded to the upper and lower ends of the second rotating shaft 15, the support rod 16 is slidably connected to the inside of the right keyboard 2, a fixing ring 3 is fixedly connected to the bottom end of the right keyboard 2, the fixing ring 3 is inside A limit rod 5 is threadedly connected, and a rotating ring 4 is fixedly connected to the surface of the limit rod 5. A limit block 6 is welded on the surface of the limit rod 5. An extension groove 9 is opened inside the right-end keyboard 2. The rotating ring 4 on the surface of the limit rod 5 cooperates with the limit rod 5 to allow the limit rod 5 to rotate and rise inside the fixed ring 3. When the limit block 6 on the surface of the limit rod 5 is adjusted to be inserted into the slot 7, the rotating ring 4 rotates the limit rod 5 inside the fixed ring 3 so that the limit block 6 on the surface of the limit rod 5 can rotate inside the limit groove 8. This can facilitate the connection and limiting of the left-end keyboard 1 and the right-end keyboard 2, and ensure the stability of the device after overall rotation and folding.

[0031] The number of the extension slots 9 is set to two, so as to facilitate folding and rotating the left keyboard 1 and the right keyboard 2 .

[0032] The extension groove 9 is symmetrically distributed with the right keyboard 2 as the center, and the interior of the extension groove 9 is fixedly connected with a support rod 16. The extension groove 9 and the support rod 16 inside the right keyboard 2 can pull the left keyboard 1 and the right keyboard 2 to cooperate with the internal fixed block 10 and the pull-out groove 11 to slide and separate to the left and right positions, and then cooperate with the first rotating shaft 13 and the extension rod 14 to realize the rotation and folding between the support rod 16 and the second rotating shaft 15 inside the extension groove 9, and then cooperate with the right keyboard 2 and the limit rod 5 at the bottom of the fixing ring 3.

[0033] The fixed ring 3 and the rotating ring 4 are symmetrically distributed with the right end keyboard 2 as the center, and the slot 7 and the limiting groove 8 are symmetrically distributed with the left end keyboard 1 as the center.

[0034] The number of the slots 7 and the limiting slots 8 is set to two, so as to facilitate the insertion of the limiting rod 5 and the limiting block 6 at the bottom end of the right keyboard 2.

[0036] The fixed block 10 and the pull-out groove 11 are symmetrically distributed with the left keyboard 1 as the center, and the extension rod 14 and the first rotating shaft 13 are slidably connected inside the pull-out groove 11. By setting the fixed block 10 and the pull-out groove 11 at the right end of the left keyboard 1, the extension groove 9 inside the right keyboard 2 can be inserted into the surface of the fixed block 10 for the left keyboard 1 and the right keyboard 2 that do not need to be folded, so as to ensure that the left keyboard 1 and the right keyboard 2 that do not need to be folded are fixed and limited.

[0037] The extension rod 14 and the second rotating shaft 15 are slidably connected inside the extension slot 9 , and the support rod 16 is slidably connected inside the extension slot 9 .

[0038] The number of the first rotating shaft 13 and the second rotating shaft 15 is set to two.

[0039] The limit blocks 6 are symmetrically distributed with the limit rod 5 as the center, and the limit rod 5 is arranged at the bottom end of the right keyboard 2.

[0040] The implementation principle of a foldable wireless Bluetooth keyboard for a computer in the embodiment of the present application is as follows: place the device in a suitable position, pull the left keyboard 1 and the right keyboard 2 to cooperate with the internal fixed block 10 and the pull-out groove 11 through the internal extension groove 9 and the support rod 16 of the right keyboard 2 to slide and separate to the left and right positions, and then cooperate with the first rotating shaft 13 and the extension rod 14 to realize the rotation and folding between the support rod 16 and the second rotating shaft 15 in the extension groove 9, and then cooperate with the right keyboard 2 and the limiting rod 5 at the bottom of the fixing ring 3, and cooperate with the rotating ring 4 on the surface of the limiting rod 5 to make the limiting rod 5 rotate and rise inside the fixing ring 3. When the limit block 6 on the surface of the limit rod 5 is adjusted to be able to be inserted into the interior of the slot 7, the limit rod 5 inside the fixed ring 3 is rotated by the rotating ring 4 so that the limit block 6 on the surface of the limit rod 5 can be rotated inside the limit groove 8, which can facilitate the connection and limitation of the left-end keyboard 1 and the right-end keyboard 2, and ensure the stability of the device after rotation and folding. By setting the fixed block 10 and the pull-out groove 11 at the right end of the left-end keyboard 1, the extension groove 9 inside the right-end keyboard 2 can be inserted into the surface of the fixed block 10 for the left-end keyboard 1 and the right-end keyboard 2 that do not need to be folded, so as to ensure that the left-end keyboard 1 and the right-end keyboard 2 that do not need to be folded are fixed and limited.

[0041] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention.
